@deepti first i let u understand what sridevi means.
Using 4digit no 4 times in somehow to make result 50,100. means apply all mathematical formula to cal it . see

@sridevi here is ur answer .

for 50.

44+4!/4 (using 4th digit 4 times)

Now for 100

(4!*4)+ sqrt(4) + sqrt(4) =100

sqrt of 4 is 2

sridevi must say i like this quiz very much.pls post like this in future also.

This is very nice one.

this is not 4 digit number. This game is about using four 4s... very good one.

This sharpens our brain. These sort of puzzles are always welcome :)

Thanks 'n' Regards,
Deepti.

Hi abid...Factorial of a number is the product of all the numbers less then and till that number. For eg 3!= 1x2x3, 2!=1x2 etc.

Now for todays puzzle:

Get the result of 124 and 282 by using four 4's
